The present invention is characterized in that the Internet phone mode detection means for detecting the Internet phone mode in the mobile phone equipped with a USB port, the audio processing means for converting the audio input and output signals, the Internet phone control means for controlling all the use for the Internet phone and the numeric keypad It is designed to be used as an internet phone handset with a dialing means for entering an Internet phone phone number. In addition, because it operates as a separate external device, you can use the Internet phone regardless of the presence or absence of the sound card.

The term "internet phone" is defined as a means for making a phone call over the Internet using a computer.

Hereinafter, described with reference to the accompanying drawings in order to achieve the object of the present invention, Figure 1 is a block diagram of an embodiment according to the present invention.

Referring to FIG. 1, the USB port 21 provided in the mobile phone 20 is a connection means with a computer. When the USB port 21 is connected to the computer USB port 12 of the computer, the mobile phone 20 immediately connects to the computer 10. It is operated as an external device. In the mobile phone 20 connected to the computer 10 via the USB port 21, the Internet phone mode switch 27 is connected to the computer 10 when the mobile phone 20 is connected to the computer 10 through the USB port 21. Pressing (27) the mobile phone is switched to the Internet phone mode, and when the switch 27 is switched to the Internet phone mode, the Internet phone program stored in the memory means of the mobile phone 20 under the control of the Internet phone control unit 23 The execution command is transmitted to the computer 10, and the computer 10 receives the command transmitted through the USB port 21 and calls the Internet phone program. Instead of switching to the Internet phone mode with the switch 27, the mobile phone mode switching means 133 of the Internet phone program stored in the memory means of the computer can switch the mobile phone to the Internet phone mode by sending a mode switch signal to the mobile phone. . When the mobile phone 20 is switched to the Internet phone mode, the Internet phone control unit 23 controls the audio input and output through the microphone 25 and the speaker 24 to be input and output to the computer 10 through the USB port 21. If the number button of the keypad 26 is pressed when the Internet phone control unit 23 is switched to the Internet phone mode, this value is input to the computer 10 through the USB port 21 so that the Internet phone can be dialed. do. The audio processor 22 converts a voice signal input from the microphone 25 into a digital signal, or converts a digital signal input from the USB port into a voice signal and applies it to the speaker 24. When the cellular phone busy processing unit 28 sends a signal indicating the busy state to the USB port 12 when the cellular phone is busy using wireless communication, the computer control unit 11 sends to the busy processing unit 132 of the Internet phone program. Causes the busy call to be processed by the computer 10. The I / O switching unit 131 converts a device to be used as an input / output of the Internet phone to a sound card or a mobile phone as a function of the Internet phone program. In addition, when the present invention is carried out with the charging device proposed by the present applicant in the 'cell phone battery charging device and method using a USB port' filed with the present invention, the cell phone can be used as an internet phone handset while charging the cell phone battery. To be a useful invention.

2 is a flowchart according to an embodiment of the present invention.

The USB port 21 of the mobile phone 20 is connected to the computer 10 (S300). The mobile phone connected to the computer 10 starts charging using the charging device (S305). When the user selects the Internet phone mode by pressing the Internet phone mode switch 27 provided in the mobile phone 20 (S310), the Internet phone control unit 23 immediately receives the input and performs an initialization operation for using the Internet phone mode. Switch to the Internet phone mode (S310). The user defines an Internet phone site address to be accessed or an Internet phone program name to be executed in the mobile phone 20 and stores it in the memory means. By the initialization signal, the Internet phone site access command pre-stored in the memory means of the mobile phone 20 is extracted and transmitted to the computer 10 through the USB port 21. The control unit 11 of the computer interprets the transmitted command to make or execute an Internet phone program (S320). At this time, the Internet phone program switches the external device to be used from the sound card to the mobile phone 20 and the sound card. Switch to the inactive state (S340). When the user inputs a number using the numeric keypad 26 of the mobile phone 20, the Internet phone control unit 23 transmits the input signal to the computer 10 through the USB port 21 and the computer 10 The signal is transmitted to the activated program, and the telephone number is dialed instead of the keyboard or the mouse (S350). If the call is connected to the dialing (S360), the Internet phone control unit 23 from the computer 10 The digital audio signal is transmitted to the audio processor 22, and the audio processor 22 receives the signal, converts it into an analog audio signal, and applies it to the speaker 24, and receives the input from the microphone 25. The analog audio signal is converted into a digital signal via the audio processor 22 and controlled to be transmitted to the computer 10, thereby making a call (S360). When the call is over, the mobile phone releases the Internet phone mode to achieve the purpose of the call. If a call to the computer 10 is received, the Internet phone program detects this and applies a ring signal to the mobile phone 20 using the USB port 21. In order for the cellular phone 20 to process the ring signal, a distinction method of the ring signal is promised in advance with the Internet phone program. The mobile phone receives the ring signal and rings the bell provided in the mobile phone. If the mobile phone 20 is busy using a wireless phone, the mobile phone 20 transmits a busy signal to the Internet phone program, thereby causing the busy processing means 132 to perform busy processing. It is apparent that the Internet phone control unit 23 is composed of a microprocessor, a memory, and an input / output interface means and operated by a program.

The present invention described above has the effect of using an Internet phone with a mobile phone without a sound card and a headset, an effect of making an Internet phone call separately from a sound card, and an effect of running an Internet phone program with a mobile phone, and dialing an Internet phone with a mobile phone. There is an effect that can be done.
